3 1 Claim. (01. 160*321) This invention relates to a window shade and more particularly to a means for adjusting the position of the window shade.

The object of the invention is to provide means for adjusting the position of a window shade that will eliminate the necessity of winding the shade by hand to thereby prevent damage to the window shade.

Another object of the invention is to provide a control means for a window shade that is easily assembled and disassembled.

A further object of the invention is to provide a control means for a window shade which is extremely simple and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a front elevational view of a window shade having the shade control connected therewith, according to the present invention;

Figure 2 is an enlarged broken side elevational view of the device of Figure 1;

Figure 3 is an inside elevational view of the upper pulley assembly;

Figure 4 is a sectional view taken on the line 44 of Figure 3; p,

Figure 5 is a sectional view taken on the line 5-5 of Figure 3 revolved clockwise 90.

Figure 6 is a top plan view of the bottom pulley assembly;

Figure 7 is an end view of the shade roller.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of the invention, the reference numeral It indicates a conventional window shade used with the window and window sill l2, Figure 1. The window shade I is supported by the pair of brackets l3 and M which are attached to the window frame l by screws it, the bracket l3 being provided with an aperture for rotatably receiving the cylindrical pintle of the roller of the window shade |0 therein. The other bracket l4, Figure 2, has a slot 8 extending inwardly from its outer periphery for snugly and rotatably receiving the shaft IQ of the upper roller assembly, indicated generally by the numeral 20, Figure 4.

The upper roller assembly or pulley comprises a housing 2| having an annular groove 22 therein for a purpose to be hereinafter described. The housin 2| is provided with a socket 6 for the reception therein of a bushing 23, said bushing being fixedly attached to the housing 2|, as by welding. The bushing 23 has a rectangular slot or socket for the reception therein of the rectangular pintle 9 of the window shade roller. Projecting from the front face of the bushing 23 is a pair of arcuately shaped flanges 24 and 25, Figure 4, for engaging between detents or dogs 26 and 21 of the window shade roller, Figure 7, so as to free the roller from the spring and connect the roller to the pulley 2| for rotation thereby.

Arranged in spaced, parallel relation below the roller assembly 20 is the roller assembly 28, Figures 1, 2, and 6, said assembly comprising an L-shaped bracket or mounting member 29 secured to the window frame l5 by the screws l6. Journaled in the bracket 29 is the headed pin 30 and rotatably mounted on the pin 30 is the pulley 3|, there being an endless cable 32 trained over the pulley 3| and the annular groove 22 of the housing 2|. Arranged in abutting relation to the pulley 3| and secured to the window frame l5 by screws I6 is a resilient arm or sprin 33 for maintaining the pulley 3| in an immobile position when not being actuated by the user.

The operation of the device is as follows: The upper pulley 2B is attached to the Window shade roller, with the rectangular pintle 9 of the roller being seated in the rectangular slot 1 of the bushing 23 and with the flanges 24 and 25 engaging between the dogs 26 and 2'! of the roller so as to free the roller from its spring and connect the roller to the pulley 2| for rotation thereby. Thus rotation of the housing 2| causes rotation of the window shade roller to thereby cause a rolling or unrolling of the window shade B on the roller, depending on the direction of movement of the cable 32. The window shade I0 is maintained in its various adjusted positions by means of the resilient arm 33 bearing against the pulley 3|. Thus, a novel means for adjusting a window shade is provided which will permit adjustments to be made without losing control of the shade and furthermore will eliminate damage to the shade, as the shade itself need not be touched.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is suscept- 3 ible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

In a window shade actuator, the combination which comprises a window shade roller having a pintle rectangular-shape in cross section extended from one end and having gripping dogs in the end from which the pintle extends, a pulley having a centrally positioned socket rectangularshape in cross section extended inwardly from one end, aligned with the shade roller wherein the said socket is positioned over the pintle extended from the roller, said pulley having spaced oppositely positioned arcuate flanges extended from the end thereof in which the socket is positioned whereby the flanges extend into the end of the roller and upon rotation of the pulley to operate a shade on the roller, the flanges engage the gripping dogs of the roller and releasing the pintle from the roller, said pulley positioned on the end 4 of the shade roller having a shaft extended from the end thereof opposite to that in which the socket is positioned and said shade roller having a pin extended from the end opposite to that on which the pulley is positioned, and a pair of mounting brackets having openings therein for receiving the pin 01 the shade roller and shaft of the pulley on the end of the shade roller.
